[Valgrind-users] How to Valgrind processes near 256GB?

[Gregory C. <gcf...@gm...>]

I have processes near 256GB, need to run valgrind to determine why, but it
runs out of memory ~60GB


==15336==     Valgrind's memory management: out of memory:

==15336==        newSuperblock's request for 4194304 bytes failed.

==15336==        62,289,825,792 bytes have already been mmap-ed ANONYMOUS.

==15336==     Valgrind cannot continue.  Sorry.

==15336==     more, depending on the tool.  On a 64-bit machine, Valgrind
==15336==     should be able to make use of up 32GB memory.

How can it's limits be increased?

Thanks
